Hints:
The input string is interpreted as an exact search pattern (with simple regular expressions allowed). Alternatively you may use the AND/OR logical operators.
Fill in only one search input field (if multiple fields are filled the "lowest" one is used) with the following exception:
*The topmost field "package file names" may be used to restrict the search space for the other searches.
Last but not least a warning: Searching in the approximative search mode or within the internal document files may be slow!
Some further infos you may find within the "Fossies" features list page.
